Is predicted to encode a protein with the following domains: SNAP-25 family; 7TM GPCR, serpentine chemoreceptor class i (Sri); Target SNARE coiled-coil homology domain; SNAP-25 domain; and Serpentine type 7TM GPCR chemoreceptor Sri. Is an ortholog of C. elegans ric-4. In C. elegans, ric-4 is involved in cholinergic synaptic transmission.
